TRACKDAY Ducati tuning available.

Microtec ECU (fuel and ignition) Tuning available

Power Commander tuning (fuel only) available

Up to 3-4 True HP improvements all through the low, mid and upper mid with a perky 2 True HP boost on top. Sweet!
(Of course that depends on how badly your bike was programmed and how much you've changed your intake and exhaust in the first place).

While the peak hp improvement numbers are what people "look at", the biggest difference in EC997 dyno tuning (over simplistic Dynojet dyno tuning) is that with the EC997's low inertia and the realtime HP readout, we can adjust the fueling at part throttle cruise, fuel and ignition to what the engine actually "wants", rather than tuning to a so-called "AFR" that it's "supposed to want".
The result is smoother part throttle, in-town cruise and maybe even better mileage.

With the proven philosophy of "tuning to Best Power and Engine Smoothness" and experience with over 30 different FI tuning programs, we can make just about every bike run better than "AFR" tuning and can definitely make better custom maps than simply dropping in a "pre-mapped" DP ECU.

With Tuneboy Software and Nemesis or Microtec ECU's, you can buy that non-Ducati exhaust system and eliminate the need for the DP ECU.
Also - if you've had your MTS custom tuned somewhere, and it still isn't as smooth or responsive as you think it could be, give us a call or email and we can set up a diagnostic dyno test with the 5 gas EGA.   Thanks - Marc

Lighter Shift Centering Spring

Just rode bike awesome shifting, smooth, smooth smooth

Lighter Shift Centering Spring

For when you decide that you want lighter feeling shift lever action for better feel.
A lighter foot shift pressure is less unsettling.
Decreases lever effort required to make a shift.
 Makes foot shift pressure more like other sportbikes.
Since you are not having to push so hard to move the lever, it's easier to find neutral.

Like your rearsets? But, no matter how you lube, shim, adjust the arcs, angles and lengths, it's still annoyingly stiff to shift?

Don't be "this guy"^

Factorini Provente

Hybrid Ceramic
Pro Shift Kit

Love the bike? Except for the shifting? Hard to find neutral?

The famous Factorini Provente Shift Kit is now available for the Ducati Twins.

Factorini Provente designed and manufactured Microbearing Detent Arm and Factorini Provente designed Detent Spring will firm up the shift feel and virtually eliminates missed shifts - both upshifting and downshifting and neutral is easier to find.

Trackday and race bikes

Eliminates the need for that old, annoying "ducati trick" of removing the "really kinda necessary" neutral detent that was done to quicken up the shifting on trackday and race bikes - all too often...... (did I mention that when I put a bike in neutral on the dyno, that I really prefer it to STAY in neutral and not "wander into 1st gear by itself? :-)

Shifts quicker.  Misses fewer shifts.
Perfect to install when working on the clutch.
Feels loads better.
Decrease Shift Kill time by 5ms to 10ms if using a quick shifter.

Remove the clutch assembly, remove the RH engine cover  - bolt in the kit.

Includes: Factorini Provente Microbearing Detent Arm and Factorini Provente Detent Spring.
(This kit does not include a clutch cover gasket)

Installation: Less than 2 hours to install with impact wrench and large socket set.

Can I install it myself?  Yes - If you can remove the clutch assembly, you can do this.

Heather rode her bike for the 1st time since I put the shift kit in. I asked if she liked it, this was her response.
"Yes! Much better. Much smoother. Thank you. :)"

8. While preventing the output shaft (the countershaft sprocket)  from turning, slowly turn the clutch shaft and shift through the gears to verify correct installation. GO THROUGH ALL GEARS - UP AND DOWN! You will have to turn the clutch shaft to allow the dogs and slots to line up and complete the shift.

9. The shift action should be slightly firmer and much quicker.

The extension of the laboratory for engines of the Swiss Federal Institute of Technology was completed in about 1935. Its architect was Rudolf Otto Salvisberg (1882-1940). He had a successful career in Berlin but returned to Switzerland after the advent of the Nazis. His architectural style was somewhat similar to that of Erich Mendelsohn. The staircase of the laboratory is in normal use but well preserved.
